The answer is 3.5. use cross product multiplication
To estimate the volume, you will use the formula for finding volume of a pyramid.
You will need to convert the height, given in feet, to yards.
(48 x 10)/3= 160 yards
You also need to convert the area of the base to square yards.
571536 ft.²/ 9 ft.² (1 square yd)= 63,504 yd.².
V = 1/3 BH, where B is the area of the base.
V = 1/3 x 63504 x 160
V = 3,386880 cubic yards
The approximate volume of The Great Pyramid is 3,386,880 yd.³.
4x^2+ 8xy - 60y^2 =48x^3y^3
They will have the same coordinate,so we can just find out x and y
3x-y=9(1)
y=-2x+11(2)
Put (2) into(1)
3x-(-2x+11)=9
3x+2x-11=9
5x=20
x=4
Put x=4 into (1)
3(4)-y=9
12-y=9
y=3
Answer is A
Step-by-step explanation:
The given function is :
(a) To find f(9), put x = 9 in the above expression.
(b) To find f(x+7), put x = x+7 in the above expression.
(c) To find f(-x), put x = -x in the above expression.
Hence, this is the required solution.
